Star Analyser Mounting Plate
Mount your SA-200 in a filter wheel.
Provided there is sufficient clearance, the Star Analyser gratings can also be mounted in filter wheels that are designed to take un-mounted drop-in filters. This optional mounting kit consists of a carrier plate, 2 additional plates that can be used as spacers, and an internally threaded collar to fix the SA200 in position in the carrier plate.
